Seaweed to tackle rising tide of obesity
Date:3/21/2010

Seaweed could hold the key to tackling obesity after it was found it reduces fat uptake by more than 75 per cent, new research has shown.

Now the team at Newcastle University are adding seaweed fibre to bread to see if they can develop foods that help you lose weight while you eat them.

A team of scientists led by Dr Iain Brownlee and Prof Jeff Pearson have found that dietary fibre in one of the world's largest commercially-used seaweed could reduce the amount of fat absorbed by the body by around 75 per cent.

The Newcastle University team found that Alginate a natural fibre found in sea kelp stops the body from absorbing fat better than most anti-obesity treatments currently available over the counter.

Using an artificial gut, they tested the effectiveness of more than 60 different natural fibres by measuring the amount of fat that was digested and absorbed with each treatment.

Presenting their findings today at the American Chemical Society Spring meeting in San Francisco, Dr Brownlee said the next step was to recruit volunteers and study whether the effects they have modelled in the lab can be reproduced in real people, and whether such foods are truly acceptable in a normal diet.

"The aim of this study was to put these products to the test and our initial findings are that alginates significantly reduce fat digestion," explains Dr Brownlee.

"This suggests that if we can add the natural fibre to products commonly eaten daily - such as bread, biscuits and yoghurts up to three quarters of the fat contained in that meal could simply pass through the body.

"We have already added the alginate to bread and initial taste tests have been extremely encouraging. Now the next step to to carry out clinical trials to find out how effective they are when eaten as part of a normal diet."

The research is part of a three year project being funded by the Biotechnology and Biological S
